A concave mirror is used as the REFLECTOR in search lights, head lights of motor VEHICLES, solar COOKERS, torches and in table lamps. A CONVEX mirror is used in automobiles such as scooters, trucks and buses as rear VIEW mirror to see the traffic behind the vehicle.

200 mExplanation:Initial VELOCITY, u = 0 m/sAcceleration, a = 4m/s²Time, t = 10sUsing the SECOND EQUATION of MOTION,S = ut + (1/2)at²S = 0×10 + 0.5 × 4 × 10²S = 0 + 2 × 100S = 200 m

As you can see in the figure the FORCE with which be gold ingot presses against the GROUND in this SITUATION is just its normal force is the force pushing the two surfaces together and the stronger the normal force the stronger the force due to friction hope it HELPED u!!

tion:the PRINCIPLE of superposition state that, the force exerted by a charge on other charge is INDEPENDENT of other charges . there fore the force on q2 due to q1 is remain same but the NET force on q2 due to q1 and q1/4 is CHANGED so, the ANSWER is F

For being with some of the COMMON IRREGULAR shapes we can MEASURE the VOLUME by the length or SIDES, breadth or height.

so it will EAT what it will GET before him.

What must be the force between the vehicle and ROAD if the vehicle is to be STOPPED with a NEGATIVE acceleration of 1.7 m S2?. Hence, the force between the automobile and the road is ˆ'2550 N, in the direction OPPOSITE to the motion of the automobile.

The children under AGE 5 YEARS have a fully developed INNER and middle ears allowing them to hear from 20 Hz to 25,000 Hz. ... As the age increases, our inner ear changes gradually which CAUSE reduce in hearing capacity from 20 Hz to 20,000 Hz.

We cannot use a clinical THERMOMETER to measure the TEMPERATURE of boiling water because the range in a clinical thermometer VARIES only between 35 DEGREE celsius to 42 degree celsius the temperature of boiling water will rise above this limit, a clinical thermometer cannot be used to measure its temperature.Explanation:hope it helped mark as brainliest

, a unit of ENERGY or HEAT variously defined. The calorie was originally defined as the amount of heat required at a pressure of 1 standard ATMOSPHERE to raise the temperature of 1 gram of WATER 1° Celsius.mark me as brainliest

This is your answer.Explanation:Decibel SCALE How much greater is the sound PRESSURE level of a typical rock band's music (110 dB) than a normal conversation (50 dB)? The sound pressure level increases by a factor of 10 for every 20-dB increase in sound level. THEREFORE, 60 dB corre- sponds to a 1000-fold increase in SPL.

The advantages of this type of barometer are its portability (inverted), and that it permits the inspection of both FREE surfaces of mercury whose difference in LEVEL have to be MEASURED. The major disadvantage is the CISTERN and the mercury it contains REQUIRE frequent cleaning to maintain the instrument's accuracy.Explanation:MARK MY ANAWER AS BRAINLIWST

Parallax is a METHOD of measuring distance to an object. ... If the distance between the observation POSITIONS is known, and the angle between them can be measured, it is a matter of simple geometry to calculate the distance to the object.Explanation:formula of parallax method:Parallax Formula: p = parallax angle in arcseconds. d = distance in "PARSECS" Writing our parallax formula in this way ALLOWS us to DEFINE a new "natural" unit for distances in astronomy: the Parallax-Second or Parsec.
